A protocol gym: prompts, tools, resources, sampling. The official README says it is not intended to be a useful server. Putting it in mcp.json burns context on a test fixture. Keep it off production hosts.
Strengths
- Official reference that hits every MCP primitive in one process.
- npx @modelcontextprotocol/server-everything, also a Docker image mcp/everything.
Known limitations
- Official README: not intended to be a useful server, but rather a test server.
- Exercises prompts, resources, sampling — easy to dump a large catalog into context.
- Lives in the reference-servers repo; no product, no support desk.
Use it when
- Building or debugging an MCP client, not doing product work.
- A conformance check that the host actually speaks prompts and sampling.
Skip it when
- You wanted a kitchen-sink of real tools — this is a test double, not a gateway.
- The agent session is billed per token; this server is noisy on purpose.
- You copied it from a tutorial into a working mcp.json.
